Inputfield spam-trap

Description

This is a plugin that inserts a hidden input field named keepempty. This will achieve the following:

Bots usually won't keep the keepempty field empty, and thus we can block any such spam attempts immediately.

Real users usually will refrain from filling in the hidden input field named keepempty.

This therefore blocks low-intelligence bots from submitting new tickets or editing the wiki.

In more detail, you can see the plugin is working if your wiki and ticket forms contain the following:

<div><input type="hidden" name="keepempty" value="" /></div>

As a result you probably will not get comment spam right after installing the input field trap. This spam prevention is meant to stop collateral spamming from bots that spam anything that has a postable <form>.
